BURRA Foods will flick the switch on its new milk powder spray drying plant and evaporator next month.

About two years in the making, the 34m high building will enable the Korumburra-based processor to produce its own skim milk, whole milk, whey powder, infant formulas, high-fat powders and protein and nutritional powders.

Previously, it contracted Murray Goulburn to produce its powders.

The plant's daily capacity for skim milk powder will be 1.04 million litres or 29 B-double trucks of milk to produce 115.5 tonnes.

The whole milk powder capacity will be 920,000 litres a day or 25.5 B-double trucks to produce 131.7 tonnes a day.

Last week the processor invited suppliers and locals to tour the plant which includes a waste water treatment plant and a new tanker drop-off area.

The tanker bay has the capacity for 20-30 tankers to drop-off milk each day, compared to only five or six a day last year.

Poowong Burra suppliers Brad and Alana McIntosh were on the plant tour and said it was good to see where their milk was going.

They also said the extra capacity would attract new suppliers and create more opportunities in the area.
